The Canadian singer, who already topped the singles chart for three weeks with the track, led the new chart ahead of Fun and Janelle Monae’s We Are Young, and Gotye’s former number one Somebody That I Used To Know.

Alex Clare’s hit Too Close – the song featured in the current Internet Explorer 9 commercial – and Nicki Minaj’s Starships – completed the top five.

The chart, compiled by the Official Charts Company, is based on data from on-demand services including Spotify, we7, Deezer and Napster, and is based on what its users are listening to rather than on sales.

‘Many many congratulations to Carly Rae Jepsen who has captured a piece of history in claiming the top spot in the very first Official Streaming Chart,’ said Official Charts Company director Martin Talbot.

‘The launch of this chart is a landmark moment for the UK music industry – and it is appropriate that such a signature Spring smash can claim this historic first.’

The new chart will be published every Monday, and will be made available in industry title Music Week as well as on the Radio 1 website.

It has been introduced in response to the increased popularity of audio streaming services – with the Official Charts Company estimating that 2.6bn audio streams were delivered in the UK last year.

Ed Sheeran – who has seven tracks featured in the top 100 – was recently revealed to have been the most streamed artist of the past year.

The A-Team singer called the honour ‘amazing’ and added, ‘Streaming services and online in general have always been an important way for me to get music out to my fans.

‘A new Official Streaming Chart that recognises another way of enjoying music can only be a good thing.’
